So, I'm using the usual Sonarr/Plex/Rclone setup and it's been working alright. I was having Sonarr write directly to the mount after downloads completed, but was noticing that it took a long time to move each file. My connection is 600Mbps down but only 20Mbps up, so my assumption was that the move operation was taking a while because it was uploading on the move. So I added --cache-tmp-upload-path to my mount command and that fixed the issue with the move operation. The problem I'm running into now is that once --cache-tmp-wait-time expires on one of the files in the tmp-upload-path and it starts to upload that file, every single file that is in the tmp-upload-path gets locked for modification, which causes sonarr to hang while.
Does anyone have a setup with similar limitations to mine that they are having success with?
